NCT03836950

Brief Summary

The purpose of this study is to examine safety, feasibility, and the behavioral and brain effects of a non-invasive treatment, repetitive transcranial magnetic stimulation (rTMS), for Veterans with Parkinson's disease or atypical parkinsonism and mild impairments in their thinking. The hypothesis is that rTMS can improve thinking for people with Parkinson's disease or atypical parkinsonism who are experiencing mild problems with their thinking ability.

Outcome Measures

Primary Outcomes (1)

  • change in NIH sponsored Executive Abilities: Measures and Instruments for neurobehavioral evaluation and re-search (NIH-EXAMINER) executive composite score

    The NIH-EXAMINER has an established 3-factor model defined by (1) cognitive control, (2) working memory (3) fluency. A confirmatory factor analysis indicates these 3-factors load on to 1-factor: executive composite score. Seven tests in the NIH-EXAMINER will be used to compute the composite score

Study Arms (2)

active rTMS

EXPERIMENTAL

For active rTMS, a butterfly coil and MagVenture MagProX100 stimulator (MagVenture, Falun, Denmark) will be used. One rTMS session will consist of 40 trains of 5sec each at 110% of resting motor threshold and 15Hz will be provided at the left DLPFC.

Device: MagVenture MagProX100 stimulator (MagVenture, Falun, Denmark)

sham rTMS

SHAM COMPARATOR

For sham rTMS, the procedure will be carried out at the left DLPFC but a sham coil will be used. The MagVenture coil has an active side and a placebo side allowing a double-blind study to be conducted. The sham system looks, sounds and feels like active rTMS.

Device: MagVenture MagProX100 stimulator (MagVenture, Falun, Denmark)

Interventions

The coil will be held tangentially to the skull at approximately 45º from the midline. One rTMS session will consist of 40 trains of 5sec each at 110% of resting motor threshold and 15Hz will be provided at the left DLPFC.
